Summary. The article presents the results of using the binary system cooling rescuer safety helmet. It is found that this allows a long time to carry out work under the influence of the presence of excess radiation protection from mechanical particles, as well as during extreme situations such as burning chemicals, magnesium alloys, electric circuits. For protection from ultraviolet radiation additionally developed a special coating with photochromic properties.
Key words: thermal radiation; protective helmet, air cooling, carbon dioxide, transparent protective shield.
